Abstract

Background:  The present study was conducted to evaluate and compare shear bond strength and marginal leakage of Fuji IX GP EXTRA and EQUIA Forte cement in primary teeth. Materials and Methods:  Forty non carious extracted primary molars were randomly divided into 2 groups; Group I (shear bond strength) and Group II (marginal leakage) with 20 teeth in each and further sub divided into two groups of 10 each i.e., Group A (Fuji IX GP EXTRA) and Group B (EQUIA Forte). For the shear bond strength, flat dentinal surface was prepared either on buccal or lingual surface of teeth and restored with their respective material. These teeth were then subjected to thermocycling and shear bond strength was determined using a universal testing machine and the values were statistically analyzed. For microleakage, class I cavities were prepared and restored with their respective materials. The teeth were then thermocycle and subjected to 0.5% basic fuchsin dye penetration followed by sectioning which were evaluated under stereomicroscope at 40X magnification to assess dye penetration and the data was statistically analyzed. Results: Results showed that the shear bond strength was highest in Group B (EQUIA Forte) 10.34±4.47 Mpa when compared to Group A (Fuji IX GP EXTRA) 5.50±1.75 Mpa and the difference was statistically significant. The microleakage score was highest in Group A when compared to group B and the difference was statistically not significant. Conclusion: EQUIA Forte cement was significantly better than Fuji IX GP EXTRA in terms of shear bond strength whereas in marginal leakage the difference was found to be statistically not significant.
